Filter holding frame

Abstract

A filter holding frame that may be used agricultural environments. The filter holding frame may include a plurality of interconnecting members with an upstream hemmed edge and downstream opposing flanges. The opposing flanges of the members may define a sealing face configured for a plurality of air filters. The members of the outer periphery of the filter holding frame may include the mounting surface and the sealing face.

 each member includes an upstream hemmed edge extending towards downstream opposing flanges, wherein said downstream opposing flanges extend outwardly away from said upstream hemmed edge; 
 said downstream opposing flanges define said outer periphery of said filter holding frame and a sealing face within each said filter cell; and 
 wherein the downstream opposing flanges define the outer periphery and the downstream opposing flanges and the sealing face within each said filter cell are substantially in the same plane. 
 
     
     
       2. The filter holding frame of  claim 1  further comprising a plurality of latches coupled to said plurality of members to position a plurality of filters. 
     
     
       3. The filter holding frame of  claim 2  wherein said plurality of latches includes a spring clip. 
     
     
       4. The filter holding frame of  claim 1  wherein said plurality of downstream opposing flanges within each said filter cell are butt welded to each other to create a substantially planar said sealing face. 
     
     
       5. The filter holding frame of  claim 1  wherein at least one said member defining said filter cell includes a slot extending from said downstream opposing flanges towards said upstream hemmed edge to receive another said member. 
     
     
       6. The filter holding frame of  claim 5  wherein said slot includes a first portion of at least one of said downstream opposing flanges, wherein said first portion of said slot receives a second portion of at least one of said downstream opposing flanges of another intersecting said member. 
     
     
       7. The filter holding frame of  claim 5  wherein said slot includes a first portion of at least one of said downstream opposing flanges and a second portion within said upstream hemmed edge, wherein said first portion is wider than said second portion. 
     
     
       8. The filter holding frame of  claim 1  is made of stainless steel. 
     
     
       9. A filter holding system comprising:
 a filter holding frame having an outer periphery and configured to support a plurality of filters, wherein each filter holding frame comprises: 
 a plurality of filter cells defined by a plurality of intersecting members, wherein each member includes an upstream hemmed edge and downstream opposing flanges, wherein said downstream opposing flanges extend outwardly away from said hemmed edge; 
 a plurality of said downstream opposing flanges defining said outer periphery of said filter holding frame combine to provide a structural mounting surface; 
 a plurality of said downstream opposing flanges within each said filter cell defines a sealing face. 
 
     
     
       10. The filter holding system of  claim 9  further comprising a plurality of latches coupled to said plurality of members to position said plurality of filters. 
     
     
       11. The filter holding system of  claim 10  wherein said plurality of latches includes a spring clip. 
     
     
       12. The filter holding system of  claim 9  wherein said plurality of downstream opposing flanges within each said filter cell are butt welded to each other to create a substantially planar said sealing face. 
     
     
       13. The filter holding system of  claim 9  wherein at least one said member defining said filter cell includes a slot extending from said downstream opposing flanges towards said upstream hemmed edge to receive another said member. 
     
     
       14. The filter holding system of  claim 13  wherein said slot includes a first portion of at least one of said downstream opposing flanges, wherein said first portion of said slot receives a second portion of at least one of said downstream opposing flanges of another intersecting said member. 
     
     
       15. The filter holding system of  claim 13  wherein said slot includes a first portion of at least one of said downstream opposing flanges and a second portion within said upstream hemmed edge, wherein said first portion is wider than said second portion. 
     
     
       16. The filter holding system of  claim 11  wherein said plurality of latches includes a plurality of intermediate brackets, wherein said intermediate bracket attaches said spring clip to said intersecting member. 
     
     
       17. The filter holding frame of  claim 3  wherein said plurality of latches includes a plurality of intermediate brackets, wherein said intermediate bracket attaches said spring clip to said intersecting member. 
     
     
       18. A filter holding frame comprising:
 a plurality of filter cells defined by a plurality of members, the plurality of members formed from a plurality of vertical support panels and a plurality of horizontal support panels; 
 a plurality of latches coupled to at least one of said plurality of vertical support panels and said plurality of horizontal support panels to position at least one filter in said plurality of filter cells; 
 wherein the plurality of vertical support panels and the plurality of horizontal support panels include an upstream hemmed edge and downstream opposing flanges, the downstream opposing flanges within each of said filter cells defining a sealing face and the downstream opposing flanges defining an outer periphery of the filter holding frame; 
 wherein at least one of the plurality of horizontal support panels downstream opposing flanges has a notch; 
 the at least one notch including a first portion sized to the downstream opposing flanges of the vertical support panels; 
 at least one of the plurality of vertical support panels has a slot to receive the upstream hemmed edge of the horizontal support panels; and 
 a plurality of latches coupled to at least some of the plurality of members to position a plurality of filters.
